Application filed September 4, 1923. Serial No. 660,666.

control type.

The primary object of the invention is to provide a vending machine so constructed that upon the insertion of a coin the mecha- I nism will operate to deliver different quan- ,tities of merchandise, such as ball gum or peanuts or the like. For instance, if a person inserts a coin in the machine and the mechanism is set to deliver one quantity, such quantity will be delivered and the mechanism will then be set for an increased amount of merchandise up to a predetermined quantity, after which themechanism will be set to repeat the measured quantity of merchandise.

With these and other objects in view, as will appear as the description proceeds, the invention consists in the novel features of construction, combinations of elements and arrangements of parts, and here-inafterto be fully described and pointed out in the appended claims.

In the accompanying drawing:

Figure 1 is a side elevation of a vending machine with parts broken away to more clearly illustrate the coin control mechanism,

Figure 2 is a horizontal sectional view taken through the machine, and illustrating the coin control mechanism, and

Figure 3 is a sectional View. on the line 33 of Figure 2.

Referring to the drawing 1 designates the casing of the vending machine having mounted therein the rotatably supported merchandise carrier 2 which is the same construction as that shown in my'Patent No. 1,464,682 August 14, 1923, This carrier is provided with a circular series of perforations 3 adapted to be engaged by the teeth of the star wheel 4, said wheel being fixed to the inner end of the operating shaft 5 which is journaled in the bearings 6 supported in any suitable manner by the wa ls 7 which is secured to the casing 1.

Fixed to the shaft 5 is a main wheel 8 having its periphery formed with a plurality of ratchet teeth 9 and circumferentially spaced stops 10, 11, 12 and 14 and a shoulder 13, the purpose of which will appear later.

A spring pressed pawl 15 is pivotally connected at one end to the wall '7 and has a tie-WE lateral arm 16 which operates in a slot 16 in said wall, said arm having a curved finger 18 adapted to engage the periphery of the wheel 8, in a manner to later appear. This pawl has its free end provided with an offset lug 17 adapted to col-operate with the wheel 18 which is rotatably supported on the wall 7, said wheel having teeth19. This wheel is provided with a plurality of spaced webs 20, 21 and 22 and resultant slot.23, 24

and 25 with. which the offset lug 17 succeS- sively engages.

A spring pressed dog 26 is pivotally supported on the wall 7 and is adapted to engagevthe ratchet teeth 9, shoulder 13 and stops 11. and 12 to prevent reverse or backward rotation of the shaft 5 after the initial 1 movement thereof in a clockwise direction] The shaft 5 is provided near its inner end with a tooth 27 which is adapted to engage the teeth 19 of the wheel 18 to impart step by step rotary movement thereto in an 'anticlockwise direction when the shaft 5 is rotated through the medium of the knob 28.

A coin slot 29 is provided to permit a coin 30 to be dropped so as to settle upon the shaft 5 and between the arm 16 and .a lateral finger 31 carried by the wheel 8.

It will be obvious that when the coin 30 is located between the finger 31 and arm 16 and the shaft 5 is rotated to the right the coin will cause the finger 18v to be raised so as to clear the stop-1O and simultaneously lift the lug 17 from engagement in the slot 25 and clear the web 20, which will permit the wheel 18 to rotate under the action of the tooth 27 a distance sufficient to permit the lug 17 to drop into the slot 23. After the lug 17 is engaged in the slot 23 the finger I 18 will drop and will ride upon the periph-- I cry of the wheel 8, the rotation of the wheel in length it will be the lug 17 will be raised and will ride on the web 21 and will ride thereon until the shaft 5 makes two revolutions, thus stepping the wheel t two teeth, after which the lug 17 will engagethe succeeding slot 24 so as to again permit the finger 18 to ride upon the periphery of the wheel 8. It will be of course apparent that when the shaft 5 and wheel 8 make two revolutions the carrier 2 will be rotated so as to deliver two balls of gum or two quantities of other merchandise. Since the webs 22 are of greater length than the other webs it will he obvious that the lug 17 will be held out of engagement with the succeeding slot 25 for a longer interval thus permitting the shaft 5 to make three complete revolutions, after which the operation will again be repeated. By varying the length of the respective webs a number of combinations may be obtained.

What is claimed is:

1. In a ventingmachine, a coin controlled mechanism comprising a shaft, a wheel rotatable with the shaft, a second wheel having webs of varying lengths thereon, a pawl, a coin chute capable of depositing a coin for engagement with the pawl, said pawl having a lug for successively engaging said webs to hold the pawl in an inactive position to permit the shaft to be rotated a predetermined number of times.

2. In a vending machine, a coin controlled operating mechanism lncluding a shaft, a wheel fixed to the shaft and rotatable therewith, a second wheel having webs of varying lengths thereon, a pawl pivotally associated with the wheels, a coin chute capable of depositing a coin for engagement with the pawl, said pawl having a lug for successively engaging said webs to hold the same in an inactive position to permit the shaft to be rotated at predetermined number of times, and means carried by the pawl for limiting the rotation of the first named wheel in one direction.

3. In a vending machine, a coin controlled operating mechanism including a shaft, a wheel rotatable with the shaft, a second wheel, a pawl, a coin chute capable of depositing a coin for engagement with the first named wheel and pawl to elevate the latter when the shaft is rotated, and means on the second wheel for varying the length of time the pawl is elevated when the shaft is rotated.

at. In a vending machine, a coin controlled mechanism including a shaft, a wheel fixed to the shaft having a finger thereon, a pawl, second wheel having webs of varying length thereon, a coin chute for depositing a coin between the finger and pawl to raise the latter when the shaft is rotated in one direction, said pawl being capable of selectively engaging the webs to hold the pawl elevated to permit the shaft to rotate for a predetermined number of times.

In testimony whereof I affix my signature.
